Pistol with carbide dies doesn't need lube, all rifle case/dies will need lube. I didn't care for the spray on lubes I used for rifles so I usually use Redding Imperial Sizing Die Wax by hand or roll on an RCBS Lube pad with RCBS Case Lube II. I don't know of any way to lube while on the press and I don't think anyone uses spray on all over the press.
